Hello,
I have found the memory used by emacs goes up monotonously, for example,
my current emacs session (up for 1 day 5 hours) takes up 101M with no
visiting files. It is the third most memory hungry application right
after the browser and a pdf viewer.
I have found calc interned lots and lots of symbols (for example:
abs\(1:\), Help\ on\ Stack, etc) into obarray. To see it:
1. Emacs -q
2. M-x calc
3. C-h v obarray
I wonder is there's a bug or a fault in calc.
Cheers,
Leo

Those are menu entries. I'm a bit surprised that they are interned, but
I don't think Calc does anything unusual in creating its menus.

Anyway, I don't see how such symbols can take up so much memory. Maybe
Leo can experiment to see if a session that does not run calc has the
same problem.

Other packages also have this problem, for example, gnus and emacs-w3m.
Oddly not all menus have that problem. For example I created a
customised-user-menu for myself in init.el and non of those strings were
interned.

From my experience, it seems 100M is common. It goes up with time. I
don't know whether that's normal. But I have never seen the memory used
goes down. When I first fire up Emacs, it uses ~25M.
